Low temperature fuel cells such as proton exchange membrane fuel cells are being currently developed to run cars and buses. Water management in these fuel cells is a key issue that needs to be adequately addressed for rapid development of the technology. The fuel cell reaction creates water that is typically carried a…

Abstract Carbon nanofibers (CNFs) are grown by catalytic CO disproportionation over ultrafine Fe3O4 catalyst at a hydrogen concentration of 0–29.17%, and the time‐depending rates of CNFs growth are continuously monitored and the morphologies of the as‐synthesized CNFs are analyzed. Increasing H2 concentration will low…
The room-temperature reaction between chromyl chloride and Sylopol 952 silicas pretreated at 200, 450, and 800 C was investigated using IR, XANES, and EXAFS spectroscopy, as well as by DFT modeling. On the silicas pretreated at 200 and 450 C, the structurally uniform sites formed by the reaction with one surface hydro…

In this work, aiming to improve the wear and/or corrosion performance of selffluxing alloys coatings, samples SAE 1020 steel were coated by thermal spray process, one of then was coated only with a self-fluxing nickel-based (NiCrBSiC) alloy and two others, in which was applied this alloy with additions of boron carbid…
In this paper, performance evaluation of catalyst for hydrogen peroxide thruster with drying condition is described. Platinum was selected as a catalyst, and alumina of pellet type was chosen as a catalyst support. Evaporation method known as general method for catalyst production was used to make the catalyst. From p…
Synthesis and characterisation of the bis-MPA based branched materials was performed. Thymine derivative was incorporated into the polymer structure as a core moiety and an active centre for H-bonding. The formation of assemblies was investigated.
In the first section, the electrical conductivity of rhodium phenylene-diisocyanide polymer is reported to be 3.4E-11 S/cm. However, the conductivity also exhibits an inverse exponential decay in air with t = 8 days. This change is attributed to the oxidation of the isocyanide functional group to an isocyanate, leadin…
Corynebacterium glutamicum has a very high capacity for the production of metabolites derived from central metabolism in which the citric acid cycle occupies a key position for the delivery of precursors for biosynthetic purposes. Succinyl-CoA is an intermediate of this cycle and this can in principle be isomerized to…
This work focused on the determination of equilibrium moisture content (EMC) of some bioplastic materials that could be used for agricultural foil mulch. Equilibrium moisture content (EMC) is very important to determine the desirable conditions of microorganism’s growth, which causes material deterioration and degrada…
Based on first-principle FLAPW-GGA calculations, we have investigated the systematic trends in structural and electronic properties of a newly discovered group of ThCr2Si2-like arsenides: SrRu2As2, BaRu2As2, SrRh2As2 and BaRh2As2. Our results show that the replacement of an alkaline earth metal (Sr - Ba) and 4d metal…
In nuclear reactors, the occurrence of critical heat flux leads to fuel rod overheating with clad fusion and radioactive products leakage. To predict the effects of such phenomenon, experiments are performed using electrically heated rods to simulate operational and accidental conditions of nuclear fuel rods. In the p…
The basic aim of the project was the fabrication of Jute Epoxy-SiC composite and study of its mechanical properties like tensile strength and microhardness and its erosion Wear characteristics in order to achieve knowledge about the method of material removal and significant factors involved in the erosion of the comp…
As-prepared amorphous zirconia $(ZrO_2)$ powders synthesized through different solution route were crystallized with increase in calcination temperature. Generally, the phase transformation from amorphous nature to crystalline forms of $ZrO_2$ was at around 450 °C, which was confirmed from the thermal analysis. After…
采用模板聚合物与金属离子配位-碳粉负载-还原方法得到的纳米复合材料P-M-C（P为聚合物，M为Fe，Co，Ni金属纳米颗粒，C为碳粉XC72）．利用红外光谱（IR）对中间产物进行了表征，结果表明所制物质为目标产物P；透射电镜（TEM）结果表明Fe，Co，Ni纳米粒子粒径多数为20-30nm，部分在10nm左右，纳米粒子均匀地分散在聚合物P上；扫描电镜的能谱（SEM．EDS）分析结果证实了Fe，Co，Ni三种元素的存在．通过循环伏安和计时电流法研究表明，碱性介质中P—M—C复合催化剂对乙醇电化学氧化具有高催化活性和稳定性；反向高效液相色谱（HPLC）结果表明乙醇氧化后的产物部分为乙醉和乙酸的混合物．
We calculated the optical absorption spectrum response of single-walled carbon nanotubes under charge doping by using density functional theory. We find that the spectrum responses can be generally divided into two categories: one is similar to those obtained from the graphene zone-folding and rigid-band model, while…
